Q.

The incorrect statement regarding chirality is:

  1. A

    The product obtained by S2 reaction of haloalkane having chirality at the reactive site shows inversion of configuration.

  2. B

    Enantiomers are superimposable mirror images of each other.

  3. C

    A racemic mixture shows zero optical rotation.

  4. D

    S1 reaction yields 1 : 1 mixture of both enantiomers.

Solution

By definition, enantiomers are non-superimposable mirror images of each other. Option (2) reverses this property and is therefore incorrect.

The other three statements correctly describe S2 inversion, the optical inactivity of a racemate, and the equal yield of enantiomers from a planar S1 carbocation intermediate.
